1. A harrow drawing and transporting device attachable to a three point linkage at the rear of a tractor, comprising: a. a frame for attaching said drawing and transporting device to said three point linkage; b. a first beam centrally and rigidly supported by said frame transverse to the line of movement of the tractor; c. spaced apart brackets rotatably mounted on said first beam; d. fork arms secured to said brackets so as to be pivotally mounted on said beam and to be movable from the horizontal to the vertical positions; e. a second beam substantially parallel to and spaced from said first beam, said second beam being fixedly mounted to the said fork arms at the pivoted ends of said fork arms; f. support fillets mounted on said first beam acting against said rotatable brackets; g. support fillets mounted on said second beam, said support fillets on both beams being relatively disposed so that compounding of the beams at the fillets takes place when the fork arms are in the horizontal or vertical positions; and h. means for trailing harrows from the compound beams so that when said fork arms are in the vertical position said first and second beams compound to act to reinforce each other in the horizontal harrow towing plane when said harrows are being towed and when said fork amrs are in the horizontal ground level position the first and second beams compound to act to reinforce each other in the vertical plane when said harrows are detached and loaded on the fork arms and then lifted clear of the ground by operation of the three point linkage.
